1 Corinthians 9:1New King James Version (NKJV)

A Pattern of Self-Denial

9 Am I not an apostle? Am I not free? Have I not seen Jesus Christ our Lord? Are you not my work in the Lord?

1 Corinthians 15:4-11New King James Version (NKJV)

⁴ and that He was buried, and that He rose again the third day according to the Scriptures, ⁵ and that He was seen by Cephas, then by the twelve. ⁶ After that He was seen by over five hundred brethren at once, of whom the greater part remain to the present, but some have fallen asleep. ⁷ After that He was seen by James, then by all the apostles. ⁸ Then last of all He was seen by me also, as by one born out of due time.

⁹ For I am the least of the apostles, who am not worthy to be called an apostle, because I persecuted the church of God. ¹⁰ But by the grace of God I am what I am, and His grace toward me was not in vain; but I labored more abundantly than they all, yet not I, but the grace of God which was with me. ¹¹ Therefore, whether it was I or they, so we preach and so you believed.
